RADD: A Replicas Adaptive Data Delivery Scheme in DTMSN

Due to the intermitted connectivity feature, it is rational to use multi-replica approaches so as to enhance the data transmission performance in DTMSN. But the majority of off-the-shelf multi-replica approaches usually generate too many message copies in the network, which may quickly exhaust the limited network resource of DTMSN. Therefore, an efficient and effective data delivery scheme needs to judge and weigh the benefits and costs due to the number of replica of messages. In this paper, we propose a new Replicas Adaptive Data Delivery protocol (RADD), which makes use of a self-adapting algorithm to reduce the number of redundant messages, and attains a good network performance with low network resource expenditure. Simulation results indicate that our proposed RADD reaches comparable or higher data delivery performance at the cost of the lower transmission overhead compared to several existing multi-replica schemes in DTMSN.
